Application filed April 4, 1924. Serial No. 704,200.

To all 'whom z't may concern:

Be it known that I, FRANCE AemoHnK, a citizen of the United States,residing at Chicago, in thecounty of Cook and State .5 of Illinois, haveinvented certain new and useful Improvements in Car Wheels, of which thefollowing is a specification.

This invention relates to new and useful improvements in car wheels,principally of the type used onvehicles adapted to travel 7 over ralls.

One of the importantobjects of the present invention is to provide a carwheel of the character described which is of such a construction as toeliminate a great deal of the unnecessary noises now made by thevehicles when-the same are traveling over the rails.

- A still further'object of the invention is to provide an improved carwheel of the above mentioned character, wherein the parts are soarranged as to enable the same to be readily disassembled whenevernecessary in order .to replace the worn parts.

A further object of the invention is to provide a car wheel of the abovementioned character, which is simple in construction, inexpensive,strong and durableand furthermore adapted for the purposes for which itis designated.

Other objects and advantages of this invention will become apparentduring a course of the following description.

In the accompanying drawing formin a part of the specification, and inwhich llke numerals designate like parts throughout the same, V

Figure 1' is a side elevation of my improved car wheel,

Figure 2 is a vertical section taken therethrough, and

Figure 3 is a sectional view taken approximately on line 3-3 of Figure2.

V In the drawing wherein for the purpose of illustration is shown thereferred embodiment of my "invention, t e numeral 1 designates the bodyportion of m car wheel and the same is cast of any suita 1e metallicmaterial in the manner well known in the art. Extendingcircumferentially around the peripheral face of the body portion is therib or flange2. The portion of the peripheral face of the body rtion 1between the rib 2 and the rear of the wheel the front face 5 of the bodyportion of the provides a brake drum 3 for the purposes also well knownin the art. 7

The body portion 1 is further provided on the opposite side of the rib 2with the annular groove 4 which is also formed in the peripheral face ofthe body portion and wheel is cut away to provide a flange 6 for thepurpose hereinafter to be more fully described. The diameter of thefront face 5- is less than the diameter of the. body portionl of thewheel as is clearly illustrated in Figure 2 of the drawing. Adapted tobe securely supported in the annular groove 4 is the packing ring 7which is formed of any suitable flexible material, preferably rubber,although it is to be understood that any other suitable material may besubstituted therefor, and I do not wish to limit myself to theparticular kind of material which is to be used. When the rubber ring 7is in position in the groove 4, the tread portion 8 of the wheel isadapted to extend therearound and the tread portion is also in theformof a ring and is provided with the annular flange 9 which extendsinwardly therefrom a cooperates with the flange 6 formed on the frontface 5 for retaining the rubber ring 7 in position within the groove 4:.As is further shown in Figure 2 of the drawing, the annular flange 9 isslightly s5 spaced from the flange 6 and this space 10 provides a meansfor permitting the inward movement of 'the tread portion 8 in such a.manner as to prevent the possibility of the flange9 on the tread portionfrom coming '9 in contact with the flange 6 on the front face 5 so as tocause any unnecessary noises. The rear face of the tread portion 8 isprovided with the usual bead 11 which is adapted to travel in the grooveprovided in. the rail over which ,the wheel rides or' is adapted to abutthe edge of a flat rail in.

'themanner well known in the art.

For the purpose of retaining the tread portion 8 in position on theflexible packing ring, I provide the retainin rin 12 which fits flushagainst the front face 0% the body portion and the tread portion resectively, and the retaining ring 12 is provided with suitable a erturesadapted to register withthe threa ed apertures 13 provided in the frontface 5 of the wheel body andsuitable fastening bolts such as shown at14:-

are adapted to extend through the openings in the retaining ring and arethreaded into the threaded openings 13 in the body portion whereby thering 12 will be securely.

clamped in engagement with the front faces of the wheel body and treadportion respec-' tively, in thejmanner clearly shown in the drawing. Anynumber of these fastening bolts maybe provided as is deemed necessary.The body portion -1 is further provided with the usual central opening15 through which is adapted to extend the axle ,.0f the vehicle in theusual manner.

By providing a car wheel of the above mentioned character, the usualnoises made by the cast wheels now in use upon convey- I rib,.a packingring of ances which travel over rails are eliminated and furthermore theparts are so arranged as to enable the same to be readily disassembledin order to replace the worn parts with new ones. Further a car wheel ofthe above mentioned character, will be strong and durable and may bemanufactured at a ve low cost.

ile I have shown the preferred embodiment of my invention, it is to beunderstood that various changes in the size, shape and arrangement ofparts may be resorted'to without departing from the spirit of. theinvention and the scope of the appended claims.

Having thus described the invention,

what I claim is 1. A car wheel comprising abody portion, an annular ribextending upwardly from the peripheral face of the body portion adjacentthe rear face thereof, said .body portion having an annular grooveformed in the periphery thereof adjacent the front face of thebodyportion and ad'acent the annular exible material in said oove, atread portion extending aroun said packing ring and abutting'the annularrib, and means for securing the' tread portion on the body portion.

2; A car wheel comprising a portion, an annular rib formed ontheperlpheral face thereof adjacent the rear face of the body portion,said body portion having an annular groove formed in the peripherythereof adjacent the front face of the body portion and adjacent theannular rib, the out face of the body portion bein cut away around itsouter edge to provi e an annular flange, a packing ring of flexiblematerial supported in said oove, a tread portion extending around sa1dpacking rin and having the front face thereof provide with an annularflange adapted to'coo erate with the annular flange on the front ace ofthe body portion, the rear face .of the tread portion abutting theannular rib, and means and having the front face thereof provide with anannular flange {adapted to cooperate with the annular flan e on thefront face of the body portion, the rear face of the tread portionabutting the annular rib, and

means for securing the tread portion on said body portion, comprising aretaining ring fitting against the front faces of the tread portion andthe body portion respectively, and fastening bolts extending throughsa1d retaining ring and threaded into the body portion.

In testimony whereof I afiix my signature.
